-
AEast
-
BSouth
-
CWest

DSouth-East

ENone of these
Answer
Correct Answer: West
Explanation
Introduction / Context:This is a pure orientation trace with multiple relative turns, starting from North.
Given Data / Assumptions:
- Start facing North.
- Sequence: Left → Left → Right → Right → Left.
Concept / Approach:Apply the turns stepwise to the current facing and record the result after each.
Step-by-Step Solution:North → Left = West.West → Left = South.South → Right = West.West → Right = North.North → Left = West.Final facing = West.
Verification / Alternative check:Combine pairs: Left+Left from North is a 180° to South; Right+Right from South returns to North; one more Left yields West.
Why Other Options Are Wrong:East/South/South-East do not match the final West orientation.
Common Pitfalls:Losing track mid-sequence; writing down each intermediate helps.
Final Answer:West
